If 3^2+4^2+12^2=13^2
Then what is 7^2+8^2+__=___

7^2+8^2+56^2 = 57^2

Step-by-step explanation:

If you look at it, you can decipher a pattern. 3x4 = 12, and then add and you get the number on the right.

So, with this we can infer it will go 7x8 = 56^2, which will be equal to 57^2

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m

10 miles
